Methylene chloride has a melting point of - 94.8°C, a boiling point of 40.0°C, a specific heat of 1.21 J/g *K for the solid and liquid, and 0.608 J/g*K for the gas. The heats of fusion and vaporization are ΔHfus of 73.40 J/g, and ΔHvap of 334.35 J/g respectively. Determine how many joules of energy are needed to heat 40 grams of methylene chloride from -171.4 ° F to 333 K. Draw out and label your heating curve. This will...

Research the melting point, boiling point, heat of fusion, heat of vaporization, and heat capacity values for ethanol. Use these values to sketch a heating curve for ethanol. The relative slopes of the rising portions and the lengths of the flat portions should correspond roughly with the values you researched. There is no need to mark any values on the x axis.

1.First, don't try that at home, it won't work or be pleasant. That aside, let's pretend you take a bottle of pure ethanol at room temperature (23 degrees Celsius) and proceed to heat it up until you produce gaseous ethanol at a temperature of 85 degrees Celsius. Assuming the ethanol in the bottle had a mass of 250 grams, how many joules of energy was required to do this? The heat of vaporization of ethanol is 841 j/g and its...

you decided to investigate how much energy it would take to get
solid acetone to gaseous acetone. So assuming you took 125 g of
-100 degree Celsius solid acetone and heated it 56 degree Celsius
gaseous acetone, how many joules of energy would be required to do
this? Acetone has a melting point of -95 degree Celsius and a
boiling point of 56 degrees Celsius. The heat of fusion (melting)
is 98 j/g and the heat of vaporization is 538.9...
